In my Patent Number 2,099,257, and in my copending application vSerialNo. 62,324, I have disclosed containers comprising a multiple wall outercarton, with an inner liner therein, such container being adapted to thereception of contents into the open mouth of the liner, at least at oneend of the container. My present invention as herein disclosedconstitutes an improvement over these containers, and also is adaptableto other types of lined containers, whether assembled in knocked-down orerect form. By my invention I am enabled to fill contents into the openmouth of a liner in a container, said open mouth being located at oneend of the container,

but to display the contents by lifting a side .or a portion of a side ofthe container after it has been packed and cl0sed,'without disruptingthe liner. At the same time I arrange to keep the liner .stretchedtightly and smoothly over the opening in the side, so provided, so as topresent the contents attractively without exposing the contents, and Ihave also provided an arrangement whereby the side or portion of theside so raised and folded back into display position, is

ther, as an alternative arrangement I may provide a construction wherebythe side so raised is folded around and down under the package, foldingtherewith also a portionv of another side of the outer carton, the partsso foldedv arranged to be secured under the container to serve as aneasel to hold the container in an attractive display position, allwithout disrupting the liner itself. Further, when it is desired toremove the contents by opening the liner itself, this operay tion isgreatly facilitated by my invention `because of the larger area madevavailable-for removal of the contents, than is possible to achieve byremoving the contents through the end of the pack- 40 age where thecontents have been inserted, and

my invention also provides a reclosure feature, and by my invention Imay also provide a' tubular liner wherein the ends of the liner aremerely folded in to overlap relation, and not secured, whereby removalthrough the open side of the outer carton is4 greatly facilitated. Theseand other objects of my invention will appear in the description and thedrawings forming part of this specification, and the scope and nature ofthe invention will be set forth in the claims which follow, to whichreference is hereby made.

In the drawings:

Fig. 2 shows the completed container, with the inner liner therein, indat or knocked-down form, 5 in which form it may be shipped to the user.

' y Fig. 3 illustrates the container shown in Fig. 2 after ithas beensquared up, andclosed at one end, the other end being openand the openmouth of the liner adapted to reception f the contents l0 to be packedtherein. l

Fig. 4 shows the finished, packed container, contents havingfbeeninserted and the other end having been closed. In this condition thecontainer is adapted for shipment. 1

Fig. 5 illustrates the abovecontainer with a portion of the side panelhaving been raised.

Fig. 6 illustrated the container shown in Fig. 5, the lid being foldedback to form a display, the t'uck on this lid portion being securedbehind the liner as indicated in the drawings, to hold the lid in thisfolded upright display position.

Fig. 6a is a section taken along line Ba-Ga of Fig. 6.

Fig. 7 illustrates an alternative form of the container illustratedabove, vthe lines of severance of the' lid portion being continuedaround the adjoining side panel as well, and the liner secured inposition without adhering the liner to this adjoining side panel,whereby, as shown in 30 the succeeding illustration, the lid panel andthe portion of the adjoining panel may be folded away from the containeritself, without'disrupting in anymanner the inner liner.

Fig. 8 illustrates the container shown in Figure 'l with the lid portionof the two side panels referred to folded under the container and the .ltuck inserted into a slot provided in the succeeding panel, whereby theentire lid portion, that is the portion that has been lifted away fromthe two panels, serves as an easel, as illustrated, thereby tilting thecontainer in an attractive tilted position for display purposes.

Fig. 9 illustrates an alternate construction, wherein the glue seam ofthe carton is adhered to the outer surface of the panel it overlies, andthe flaps articulated to the lid panel -are connected to the lid panelby lines of severance.

Fig. 9a is a plan view, reduced in scale, of the blank for the boxofFig. 9.

Fig. 10 illustrates the 4container shown in Fig. 9 after it has beenerected andlled with contents and the ends closed, in the same manneras'de- 55 the lines of severance provided therefor, exposing thereby acomplete side, without disrupting the liner itself. v

Fig. 12 illustrates another alternate construction, wherein medial foldlines are provided ontwo opposite panels, by which the carton is foldedin fiat or knocked-down form, the inner liner being closed independentlyat one end of the container. 'I'he lid arrangement is similar to `thatshown in Figure 9, except that the lines/of severance in thisillustration are located as shown, so that the lid which can be raisedis only a portion of one panel, and, not the complete panel itself asillustrated in Fig. 9.

Fig. 13. illustrates a lined carton which has been assembled in erectform, the vcarton itself being made according to my preferredconstruction as illustrated in Fig. 1,`squared up into erect form andone end closed prior to the introduction of the inner liner. Prior tothe introduction of the inner liner within the outer carton, adhesivehas been provided to secure. the liner to the carton at the desiredsurfaces, but provided so as not to interfere with the subsequentraising' of the lid panel on the side.

For the sake of clarity in referring-to the drawings, we will refer tothe sides or main body panels of the outer carton, simply as panels andconsider that'portion of the sides of the outer carton which is to beraised, as the lid panel Whether this portion adapted to be liftedcomprises merely a portion of one of the panels, the entirefpanel, ormore than a single panel, as is the case inv Fig, 5. The ap provided onthe carton to retain the carton in tubular form. by gluing or otherwise,will be referred to as the glue ap and the end'flaps articulated to thepanels for enclosing the end of the container' will be referred to asthe closing aps. 'I'he blank shown in Fig. 1 has four vpanels I, 2, 3,and 4, there being transverse lines of severance 5, 5 in panel 4, theportion of this panel between the lines of severance serving as the lidpanel. As c an be noted, these lines of severance continue through theglue ap 6, and in this case the lid panel has been provided withsuitable lines of cut 'I and fold, to provide a suitable for subsequentfolding back` into display position. while if the lid is to servemerelyas a means for subsequently opening the container to remove thecontents, and not for display purpjoeeathc lines of cut and fold in thislid panel g'lhe-shaded portions 9 indicate the areas ofthe-inne'r-surfaceof the'carton-which are to be adheredto the'vpre-formed liner.' It will be noted t no "adhesive is provided on theinner suryfacelof the;' lid-panel`s,' or on the inner-surface oftheportlomof-the glue flap which are articulated tothe' lid'lnel.

FIg. 'shows'the blank illustrated in Fig. 1- the preformed liner hasbeen introduced, 70 and the carton has been folded and secured about theliner. It should be noted that the portion of the glue ap which isarticulated to the lid panel is not adhered to the panel I whichoverlies it, b ut the adjoining portions of the glue flap 75 have beenso adhered to said'panel I. thereby serving to hold the carton intubular form. When the carton has been so folded about the innerliner,`the liner IIIy will be adhered to the inner surfaces of the cartonalong the shaded areas shown in Fig. 1. In this particular illustrationY the inner liner is a exible pre-formed tube, with the overlappingportions indicated at II, not

adhered to each other.' However, when the inner liner has been so foldedand placed within the outer carton, it will retain its tubularcondition, but the absence ofadhesion between the overlapped portions ofthe liner serves to simplify the opening of the liner from the sideafter the `lid panel has been lifted subsequently. It will be noted fromthe drawings that the overlapped portion of the liner is placed so as toface upwardly, that is to appear in the opening exposed on theside ofthe carton when the lid panel has been lifted. In instances where asealing of the liner is desired, the lengthwise seam will be sealedbefore introduction of the tube and it may also be desirable to seal oneend of the tube forming a fiat bag for securing within the carton.Materials which are transparent and still highly impermeable arevavailable for such` liners.

In this particular illustration the containerr is designed to be closedby inter-folding the ends of the liner and the closing flaps.

Figure 3 illustrates the. container after the carton has been squared upinto erected form, and one end so closed. In closing this end,` theclosingaps I2 and,l I3 areflrst folded inwardly, serving to fold in acorresponding portion of the open end of the liner with them, and theclosing flaps Nos. Il and I5, are folded into overlapping relation.'I'he flaps may be secured by adhesion, or by locking, or by any oneof anumber of wellknown means.

It should be notedfrom the illustration that I prefer to have the end ofthe liner extending beyond the end of the closing aps which. are the rstmentioned flaps just referred to. In this manner when these flaps arefolded in, the liner will lcover the edges or ends of same on theinterior of the container, so that no portion of the outer carton itselfis in contact with the contents. When the-contents arev of a greasynature for example, such as doughnuts, this feature is ofimportancebecause the liner may be made of grease-proof material such asglassine or Cellophane or the like, 'Whereas the outer carton may becardboard or other material which` .is not grease-resistant, so it isimportant that introduced and the contents filled, this end may beclosed in the same manner as the end just described was closed. The.container is now in the form illustrated in Fig.'4, which form providesa package, the contentsbeingheld'within the inner liner, and the innerliner being adequately secured to the outer carton so that it is heldmanufacturer of food ship the package,

Fig. 5 shows the with the lid raised. Since the portion of the glue flapwhich is articulated to the lid panel Products or the like can 'has notbeen adhesively secured in position. it

from shifting. etc.. and in this condition the package illustrated in 4,but *I glue flap articulated to the lid panel serving as.

is extremely simple to lift this lid. panel, and the linesof severance 5can either4 be complete cuts througli---the carton itself, or may belines of perforation or the like. It can also be seen that the liftingof this lid panel in no way` disrupts the inner liner, and the liner isheld securely in taut position over the opening, providing a neat andattractive appearance, and providingvv full protection for the contents.

As shown in Fig. 6, this lid panel may be folded back into displayposition, the portion of the a tuck, this tuck being placed between theliner and the panel 3. It should be noted that the liner has been leftunsecured to the upper part of panel 3, to provide clearance space forthe tuck in this case. This serves to retain the lid panel folded backinto display position, providingv as can readily be seen, an attractivebox for the merchant or retailer to place upon the counter, withexcellent display value, and at the saine time with the contentsprotected by the inner liner so as not to be exposed and still receivethe full benefit of whatever protective qualities which are provided bythe inner liner.

In the modification shown in Figs. 'l and 8, the lines of severance inthe lid panel have been con-A tinued into panel 3 as at 5a. In this casethe liner is so glued to the carton that the portion of the lid panelformed from the panel 3, is unsecured to the liner, whereby as shown inFig. 8 the lid panel, comprising parts of b oth panels 4 and 3, can befolded back around under the carton, without disrupting the inner linerin any way. As also illustrated a slot I6 has been provided in panel 2,in which the tuck may be inserted, so that the lid panel which has beenfolded around and under the package serves as an easel, giving thepackage a tilt providing an attractive and effective unit on thecounter, and here again this has been accomplished without disruptingthe inner liner.

In the alternate construction shown in Fig. 9, the entire glue flap 6has been secured to the panel I, which it overlies, and in this embodi-`ment it should be noted that the glue ap overlies rather than underliesthe panel referred to. In this construction as illustrated,.the glueflap has been increased somewhat in width over that actually required tomake an effective seam, the reason for this being that the glue seamitself can be confined to a relatively limited area as i1- lustrated atI1, making it simple for the user or dealer tol insert a pencil or othersharp pointed object and rip through this glue seam,v thereby freeingthe glue flap from the panel to which it was secured. Thereafter ifdesired to reclose the lid, the glue ap can then serve as a tuck for thelid panel. In this particular embodiment also the transverse lines ofseverance I8 serve to articulate the closing flaps to thev lid panel, so

.that after the glue flap has been released by theA seam being broken asjust described, the lid panel.

may be raised to expose the complete side of the container. The'liner issecured to the closing flaps along line I9, I 9, in this construction sothat it is not released when the entire panel 4 is raised.

In Fig. 10, the container in Fig. 9 is shown with the ends sealed, thecontents being therein, I

and Fig. 11 snows this container with the lid raised, as Just described.In Fig. 12 the carton illustrated has intermediate lines of fold 20, inthe panels I and 3,

on which the lcarton is folded about the inner adjoining the closed endof the liner by folding in and securing the closing flaps, and after thecontents have been introduced the open mouth'of the liner can be sealedindependently if desired, and the closing aps at this end foldedinwardly, providing a. completed Asquared package in erect form, inwhich the inner liner is independently sealed. 'Ihe lid panelarrangement in this embodiment is similar to that shown in Fig. 9,except that instead of an entire panel being utilized, the transverselines' of severance 23 defining the lid panel incorporate only a portionof panel 4, which is an alternate lid arrangement adapted to either thestyle container shown in Fig. 12, orto the previously described type.

In this form the panel defined by the lines 23 is not adhesively securedto the liner, and the tabs 23a, 23a, are adhesively secured as well asthe ap 6, to the outside of the wall I ofthe carton, as shown. l

Inl Fig. 13 the container is formed from a blank as shown in Fig. 1, theblank being folded and glued in tubular form, and thereafter squared upand one end being closed by by the closing ilaps. Thereafter, an erector squared up tubular liner, which may have one end closed if desired,is introduced into the erect carton, and adhesive provided so as tosecure theliner to the carton, ex-

cept for the portions of the carton which forml mouth of the liner,which open liner mouth is exposed between theclosing flaps at one endthereof. Thereafter the liner and the closing flaps at this end areclosed, and subsequently the .contents may be displayed by liftingthe'lid panel,

which is accomplished without disrupting the liner so that the contentsmay be displayed without losing in any way the eiectiveness of theprotective qualities of the inner liner. Upon lifting the lid panel alarge liner area is exposed, and i it is desired to open the liner andremove the contents through this exposed area, it is extremely easy todo so, much simpler than it would be were it necessary to remove thecontents through the end of the container where they Were in serted. y

Further, the lid panel provides a very effective closure feature, as forexample after being placed on the counter in display positionwith theliner V remaining intact, the lid panel can be again -brought intoclosing position to protect the liner,

while for example it is carried from the store to the home, and thissame reclosure feature is of importance once the liner has been opened,as

'the lid panel can be placed intol closing position 75A securely. as is'often desired. during the time when the contents are being consumed.I

To achieve the maximum display value, it is obvious that the liner maybe made of Oellophane'or other transparent sheets, and of course theliner can also be made of any suitable'ilexible material to providethedesired protective qualities for the contents.

It can b e seen that by my invention, I have l0 providedA means wherebythe container can be opened andreclosed if desired, for displaypurposes, without disrupting the liner and the contents within the linercan be effectively displayed without exposing the contents, and withoutcausing the contents to lose the benets of the protective qualitieswhich may be'inherent in the liner material.

As pointed out, it is immaterial in my invention herein disclosedwhether the liner is interfolded with .the aps of the carton or whetherthe ends of the liner are closed independently of the closing iiaps ofthe carton. vAs explained in connection with Fig..i 1, I may also ifdesired, provide a folded pre-formed tubular liner instead of a lineradhered at its tubular -seam if desired, in order to facilitatedispensing of the contents.

It is obvious also that-the. liner could be made of 1 several materialscombined, for example a Cellophane face at the portion underlying thelid 80 panel, and other material at the portions adjoining other panels.Such modifications can be made without departing fromthe spirit or scopelof my invention, and having thus described my invention what I claim asnew and desire to se- 8l cure by Letters Patent is as follows:
